Solution:
The point lies on the curve
Now,
Since the tangent makes an angle with x-axis.
Slope of the tangent = 2
Solving (i) and (iii), we get
If the tangent to the curve at is inclined at an angle with x-axis, then
The point lies on the curve
Now,
Since the tangent makes an angle with x-axis.
Slope of the tangent = 2
Solving (i) and (iii), we get
